Synovial chondromatosis affecting a digital proximal interphalangeal joint

Area of Science:

• Orthopedics
• Rheumatology
• Radiology

Background:

• Synovial chondromatosis is a rare benign condition characterized by the formation of cartilaginous nodules within a joint.
• It most commonly affects large joints like the knee and hip, but can occur in any synovial joint.

Observation:

• This case details synovial chondromatosis impacting an interphalangeal joint of the hand.
• Pre-operative radiographic imaging did not definitively reveal the extent or presence of the disease.

Findings:

• The diagnosis was confirmed intraoperatively, highlighting the limitations of standard radiography in subtle cases.
• Articular synovial chondromatosis can present insidiously, mimicking other common joint pathologies.

Implications:

• This case underscores the importance of considering synovial chondromatosis in the differential diagnosis of hand and finger joint pain and stiffness.
• Clinicians and radiologists should maintain a high index of suspicion for this condition, even with non-specific radiographic findings.
• Early and accurate diagnosis is crucial for appropriate management and preventing long-term joint damage.
